I have the ECO 20 with autoturn cradle and I love it for several reasons... it's reliable, extremely easy to clean, holds temp and humidity well, very easy to use, and takes up little space.
I have 4 GQF Sportsman 'bators but will be using my Brinsea for my next batch of eggs as there are only about 20 eggs and I don't want to fire up the big cabinets for such a small batch. I'm quite confident that the eggs will do just as well in the Brinsea.
Good luck with your purchase, whatever you decide on!
I have the 20 advance with cradle. got that instead of the eco because of a good price on ebay. Really not a big advantage over the ECO. These are excellent incubators for the small hobby breeder. The tray can hold an honest 26 chicken eggs but it would be more than a little tight with a hatch of more than 15 or so. See my pics on todays thread with 15 average size chicks in a 20. Very happy with mine.
